Blender will not fully open
I had the same problem recently. It's probably something else, but, please, try to run blender via CMD (windows+R : CMD). If it's the same issue as me, you could have this error : 


  EXCEPTION_ACCESS_VIOLATION


If it's that error : you just have to reinstall blender 2.76b. (It worked for me on my old computer with a windows 10). Somebody here had the same issue and report the bug (I think)

If it's not, you could copy/paste the error here.
